The present invention provides: a reflector 3 having a main reflector 2U and second additional reflection surfaces 9, 9; a semiconductor-type light source 5U; a light shading member 12U having first additional reflection surfaces 15U, 15U; and a shades 13U, 13U, 14U, 14U. The illuminating source can also be moved to indicate a change in a predetermined trajectory or target position where a new position andor orientation of the object is determined based on the signal received in the waveguides and the object is controlled to change the predetermined trajectory or target position to the indicated new predetermined trajectory or new target position. The latch assembly further includes a latch fitting coupled to the fixed portion of the ramp assembly.
